IPC: H01L21/285
Filed: 1999-10-02
Abstract: PURPOSE: A method for producing a semiconductor device is provided to contain a metal silicide layer of high melting point having excellent heat resistance on a semiconductor substrate for improving reliability. CONSTITUTION: A field oxide film(101) is formed on a semiconductor substrate(100) for mounting a gate oxide film and a gate polysilicon film successively. Then, a gate electrode(104) is formed by patterning the gate polysilicon film by using a photo lithography process and a dry-etching method. And a side wall(105) made from the silicon oxide film is formed on the side surface of the gate electrode, and an N-typed or a P-typed gate electrode(106) and an N-typed or a P-typed diffusion layer are formed. And then, a natural oxide film formed on the silicon surface is eliminated for sputtering at the substrate temperature for 400°C to evaporate 15nm of cobalt layer and to heat-treat the substrate. Therefore, a metal silicide film having a thickness for 25nm is formed in the area for the cobalt layer and the silicon to contact each other. Then, the cobalt layer is selectively eliminated by a wet-etching method for phase-shifting the metal silicide film with 25nm to a metal silicide film(108) with 50nm. Herein, the uniformity of the metal silicide film is improved by adjusting the amount of ion-injection and heat-treatment.
